Application filed March 8, 1926. Serial No. 93,239.

This invention relates to register front fasteners. More particularly itbelongs to that class of contrivances intended to secure the front oropenwork plate or grating common to warm air registersin the frame orsurrounding housing.

It is an object of this invention to produce a front fastener of simplecharacter, readily and cheaply manufactured and applied, that may bequickly placed in position and as quickly removed in case of neces;sity, and which will be at'all times held securely when in the frame,and which will present no unsightly protuberances, attachments orextensions, the whole front being left practically flush with the faceof the frame. By reason of the simplicity of this invention no specialskill or tools are called for to deposit the front in the frame and tofirmly and strongly fix it in place. It is a further object of thisinvention to provide a fastener of the nature mentioned which willcomprise parts of special form, construction and arrangementparticularly well adapted for the purposes intended.

In the accompanying drawings the special construction and disposition ofthe com- Y bined parts of this invention in its preferred form areillustrated. Fig. 1 is a front view 30 of all the parts assembled. Fig.2 is a vertical section on the broken line 22 of Fig. '1. Fig. 3 is afull size sectional view of the lower portion of the frame as set forthin Fig. 2, showing the particular form and arrangement of the depressionin the face of the frame, and showing also the communicating slot. Fig.41 is a side view partly sectional showing the screw fastener and theeccentric turning disk borne thereby on 4.) the inside ofthe edge of thelower portion of the front. Fig. 5 is a face view of the eccentric orlooking disk.

, Throughout the drawings and descrip tion the same number is used torefer to the same part.

Considering the drawings, the register frame 1 has a seat 2 formed toreceive the openwork front. The upper part of the frame 1 has twoseparated slots 3 and 4t, and

those slots are located usually at the inner edge of a raised portion 5of the frame which forms the boundary outwardly of the seat 2 for thefront. Two small tongues 7 and 8 are constructed to be introduced intothe slots 3 and 1 to hold the upper edge or the front in place. It willbe noted in Fig. 2 that the frame 1 has an opening 6.

The front or grating, which may be of any selected pattern as to itsopenwork, is designated by the reference number 9.

Passing through the lower edge of the front 9 will be noted'the screws10 and 11, each having a squared shank 12 as shown in Fig. 4, to fit thesquared orifice in the firs tener disk 13 as illustrated-in Fig. 5. Theshank of the screw 11 is headed as shown at 1st in Fig. 4 to hold thedisk and shank together. It is thought to be clear from the drawingsthat the disk may be turned by inserting a screwdriver in the slot ofthe screw head.

. Considering Fig. 3 it will be observed that the frame 1 has adepression 15 formed in the face thereof immediately above the raisedportion 5. Usually the rear wall of the depression 15 is furtherdepressed or countersunk as at 16 to receive the head 14 of the shank 12of the turning screw-headed member 11, in order that all the parts mayfit together and avoid projections which would tend to detract from thegood appearance of the register as a whole. In Fig. 3 alsoit will beseen that the depression 15 has a communicating slot 17, and it is intothis communicating slot that the disk 13 is turned to secure the front 9in position in p the frame 1.

In the operation of this invention, if by means of a. screwdriver thescrews 10 and 11 are so turned as to bring the disks into thedepressions 15, the lower edge ofthe front may be raised from the seat2, and the two small tongues 7 and 8- easily withdrawn. This may be veryquickly and easily accomplished, and the replacement is made with likeexpedition. The sectional View, Fig. 2, shows that projections orextensions are reduced to a minimum. 7 I

Having now described this invention, and explained the mode of itsoperation, what I claim is 2- p The combination with a register frame,of

an open work front for the register, means for securing the upper edgeof the said front in the frame in detachable relation, the lower"portion of the said frame; haying spaced" depressed portions formingrecesses in the frame open at the bottom, and releasble securing e c sarries-1; y he aidi front and constrncte to-be passed intotle saiddepressions of the frame, the said devices having portions arranged tobe turned 10 into engagement With, thesaid open bottoms ofthedepressions. v I V In testimony whereof I afiix my signature.
